' RAIL ANCHOR.

Application filed August 25, 1921.

T 0 all "whom itmay concern:

Be it known that I, HAROLD G. WARR, a citizen of the United States, residing at Park Ridge, in the :county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to rail anchors, and has for its principal object the provision of an improved one-piece rail anchor having jaws for engaging opposite edges of a rail base with spring pressure, and adapted to take a firm shackle hold on the rail during the presence of'creeping pressure on the rail.

A more specific object of the invention is to provide an improved one-piece anchor constructed so that its jaws are forced apart and the body of the device subjected to a tortional strain when the device is applied to and in its operative position on a rail. In this connection, the invention contemplates an anchor having a normally flat body portion and a jaw portion which is so formed that the anchor. during its application to the rail, is subjected to a twisting strain'and thereby exerts spring pressure against the upper and lower surfaces of the rail base.

The invention consists in the provision of a new and improved one-piece anchor constructed as hereinafter described and claimed, for carrying out the above stated objects and such other objects as will appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein Fig. 1 is a plan view of the rail anchor.

ing its normal configuration when free of the rail.

Serial No. 495,387.

Fig. 6 is a plan view of a modified form of device.

Like characters of reference designate like parts in the several figures of the drawmgs.

In the drawings, 10 designates a railroad rail, and 11 one of the cross-ties on which the rail. is supported.

The rail anchor consists of a flat piece of metal, cut away as indicated at 12, to provide an upstanding shoulder 13 adapted to bear against one of the vertical edges of the rail base and a notch 14 providing a jaw portion 15 having an angularly disposed lip 16 adapted to fit over the other edge of the rail base. The other end of the device is formed with a return bent portion 17 which extends forwardly toward the tie, and terminates in a flat portion adapted to abut against one of the vertical faces of the tie 11. The vertical edge of the tie-abutting portion 18 is recessed as indicated at 19, to provide a jaw adapted to fit over the edge of the rail base at a point adjacent the tie. The portion 20 of the jaw above the recess 19 is beveled as shown at 21. to facilitate the application of the device to the rail, as will be hereinafter described. The device is made sothat the effective distance between the jaws 15 and 19, when the device is free of the rail. is less than the distance which the device has to span when being applied to or in operative position on the rail. In other words, in applying the anchor, the jaws 15 and 19 have to be forced away from each other. The engagement of the anchor with-the rail base preferably also is such that the body of the anchor is under tortional strain when applied to the rail. To accomplish this, the notch 14 is formed so that the dimension indicated at B will be less than the thickness of the rail base at the point. engaged by the liplwhen the device 1s in 1ts operative position.

In the drawings. it will be seen thatthe lower edge 22 of the lip 16 inclines downwardly' toward the rail base. In order to compensate for the difference in the vertical dimension B and the thickness of the rail base at the point engaged by the lower ed of the lip 16, the lip 16 is bent backward y so that the efi'ective distance between the upper edge of the bottom portlon Of the anchor and the edge of the lip 16 is increased by tilting the anchor on a substantially horizontal axis. \Vhen the device is tilted in the above manner, the vertical edge 23 of the notch 14 may be brought into contact with the vertical edge of the rail base. Under this condition the jaw 19will be out of line with the opposite edge of the rail base; that is to say, below the same; In order to bring the jaw 19 into operative engagement with the rail base. it is necessary to twist or strain the anchor. During this operation the beveled edge 21 rides over the edge of the rail base until the latter enters the recess 19 of the return bent portion of the anchor.

It will be seen that the device. as described above, will hold the rail against creeping forwardly, that is, in the direction from the anchor toward the tie 11. By forming the anchor so that the jaws 15 and 19 have to be spread apart, and the body portion of the anchor subjected to a tortional strain when the device is in its operative position, the device will take a firm spring grip on the rail, so as to resist the tendency of vibration, or other disturbing influences, from loosening its hold on the rail. The anchor, however, will permit the rail to move in the opposite direction without carrying the anchor with it,.and this is desirable because the rearward movement of the anchor is likely to be interfered with by the ballast. The tie abutting portion 18 is preferably made relatively short so as to confine its engagement with the tie to a point near the edge of the rail base. \Vith this construction the anchor may assume different diagonal positions without effecting a substantial change in its point of contactwith the tie.

In Fig. 6 I have shown a modified construction in which the tie abutting portion 18 is curved backwardly from the tie so that the abutment will bear at the same point on the tie regardless of the particular diagonal position assumed by the body portion of the anchor. In other respects, this anchor may be made the same as that shown in Figs. 1 to 5inclusive.

This application is a continuation in part of my co-pending application Serial No. 449,077, filed March 2, 1921, as a renewal of my application Serial No. 295,555 filed May 8, 1919.
